A Web framework is a collection of packages or modules which allow developers to write Web applications or services without having to handle such low-level details as protocols, sockets or process/thread management. As a developer using a framework, you typically write code which conforms to some kind of conventions, with the benefit being that most of the code can be concerned with the logic of the application, rather than working out how to process incoming network messages, spawn processes, work out which part of the application should be invoked, and so on. Some frameworks can be considered moderately low-level in that they provide abstractions only for certain things (eg. incoming requests, outgoing responses, state handling), whereas other frameworks provide many more abstractions and mechanisms (eg. database access, presentation of Web pages). Since a non-trivial Web application will require a number of different kinds of abstractions, often stacked upon each other, those frameworks which attempt to provide a complete solution for applications are often known as "full-stack" frameworks in that they attempt to supply components for each layer in the stack. == Full-Stack Frameworks == These frameworks probably cover every area from providing a Web server through database access and persistence to templating and presentation: * ["4Suite"] * CherryPy (2.2.0 Released 2006-01-27)CherryPy is a pythonic, object-oriented web development framework * ["Cymbeline"] (1.3.1 Released 2005-12-09)application server framework, including functionality such as DB and arbitrary object pooling, web servers, persistant object repository, and a text console * ["Django"] (0.95 Released 2006-07-29) Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design * ["Karrigell"] (2.3 Released 2006-06-24) designed to be really simple to use : integrated web server and data base * [http://plone.org/ Plone] (2.5 Released 2006-06-17) Plone is a Python based popular contet management system running on Zope application server * [http://pythonpaste.org/ Python Paste ] (0.4.1 Released 2006-02-18) brings consistency to Python web development and web application installation, providing tools for both developers and system administrators * [http://pylonshq.com/ Pylons] (0.9 Released 2006-07-27) Pylons is a lightweight web framework emphasizing flexibility and rapid development.

A Web framework is a collection of packages or modules which allow developers to write Web applications (see WebApplications) or services without having to handle such low-level details as protocols, sockets or process/thread management. The majority of Web frameworks are exclusively server-side technology, although, with the increased prevalence of AJAX, some Web frameworks are beginning to include AJAX code that helps developers with the particularly tricky task of programming (client-side) the user's browser. At the extreme end of the client-side Web Frameworks is technology that can use the web browser as a full-blown application execution environment (a la gmail for example): see [[WebBrowserProgramming|Web Browser Programming]] for details. As a developer using a framework, you typically write code which conforms to some kind of conventions that lets you "plug in" to the framework, delegating responsibility for the communications, infrastructure and low-level stuff to the framework while concentrating on the logic of the application in your own code. This "plugging in" aspect of Web development is often seen as being in opposition to the classical distinction between programs and libraries, and the notion of a "mainloop" dispatching events to application code is very similar to that found in [[GuiProgramming|GUI programming]]. Generally, frameworks provide support for a number of activities such as interpreting requests (getting form parameters, handling cookies and sessions), producing responses (presenting data as HTML or in other formats), storing data persistently, and so on. Since a non-trivial Web application will require a number of different kinds of abstractions, often stacked upon each other, those frameworks which attempt to provide a complete solution for applications are often known as '''full-stack''' frameworks in that they attempt to supply components for each layer in the stack. Many frameworks now provide an element of customization in their support for the above activities and abstractions, utilizing [[WebComponents|components]] in that they provide abstractions only for certain specific things. As a result, it can be possible for you to build your own full-stack framework almost entirely from existing components. == Popular Full-Stack Frameworks == A web application may use a combination of a base HTTP application server, a storage mechanism such as a database, a template engine, a request dispatcher, an authentication module and an AJAX toolkit. These can be individual components or be provided together in a high-level framework. These are the most popular high-level frameworks. Many of them include components listed on the WebComponents page. ||Name ||Latest version ||Latest update date ||description || ||[[https://www.djangoproject.com/|Django]] ||3.2.3 (LTS) ||2021-05-13 ||The Web framework for perfectionists (with deadlines).

'''Do not''' invent special categories in order to elevate the profile of certain projects. '''Do not''' merge categories and put frameworks into a miscellaneous category. * '''Do not''' add links to projects unless they are Web frameworks. Instead, use the WebComponents, WebServers, [[Templating]] pages, or any page referenced by WebProgramming. * Some frameworks are not actively developed or maintained. '''Do not''' just move entries into the "Discontinued/Inactive Frameworks" section without at least doing some investigation first. * Popular is a bit of an arbitrary classification. For something to be considered popular a good guideline would be that it is in the top 4000 packages as per [[https://hugovk.github.io/top-pypi-packages/|Top PyPI Packages]]. And some basic editing advice: use the preview button when making edits, rather than leaving tens of micro-changes in the history. |

1. Web Frameworks for Python
A Web framework is a collection of packages or modules which allow developers to write Web applications (see WebApplications) or services without having to handle such low-level details as protocols, sockets or process/thread management.
The majority of Web frameworks are exclusively server-side technology, although, with the increased prevalence of AJAX, some Web frameworks are beginning to include AJAX code that helps developers with the particularly tricky task of programming (client-side) the user's browser. At the extreme end of the client-side Web Frameworks is technology that can use the web browser as a full-blown application execution environment (a la gmail for example): see Web Browser Programming for details.
As a developer using a framework, you typically write code which conforms to some kind of conventions that lets you "plug in" to the framework, delegating responsibility for the communications, infrastructure and low-level stuff to the framework while concentrating on the logic of the application in your own code. This "plugging in" aspect of Web development is often seen as being in opposition to the classical distinction between programs and libraries, and the notion of a "mainloop" dispatching events to application code is very similar to that found in GUI programming.
Generally, frameworks provide support for a number of activities such as interpreting requests (getting form parameters, handling cookies and sessions), producing responses (presenting data as HTML or in other formats), storing data persistently, and so on. Since a non-trivial Web application will require a number of different kinds of abstractions, often stacked upon each other, those frameworks which attempt to provide a complete solution for applications are often known as full-stack frameworks in that they attempt to supply components for each layer in the stack.
Many frameworks now provide an element of customization in their support for the above activities and abstractions, utilizing components in that they provide abstractions only for certain specific things. As a result, it can be possible for you to build your own full-stack framework almost entirely from existing components.
1.1. Popular Full-Stack Frameworks
A web application may use a combination of a base HTTP application server, a storage mechanism such as a database, a template engine, a request dispatcher, an authentication module and an AJAX toolkit. These can be individual components or be provided together in a high-level framework.
These are the most popular high-level frameworks. Many of them include components listed on the WebComponents page.

Klein (19.6.0 released 2019-06-07) is a micro-framework for developing production-ready web services with Python. It is 'micro' in that it has an incredibly small API similar to Bottle and Flask. It is not 'micro' in that it depends on things outside the standard library. This is primarily because it is built on widely used and well tested components like Werkzeug and Twisted.
MorePath (0.18.2 released 2019-01-22) Morepath is a Python web microframework, with super powers. It uses routing, but the routing is to models. Morepath is model-driven and flexible, which makes it expressive.

WebStack (1.2.7 Released 2007-10-29) - very lightweight, requiring layers of extra technology (such as XSLTools and others) to match full-stack frameworks in feature comparisons
WSGIServlets (1.0.1 Released 2011-11-09) - lightweight, object-oriented framework that doesn't get in your way. Intuitive class hierarchy makes coding WSGI applications, middleware or full-blown CMS and frameworks a simple task by providing developers a rich set of tools out-of-the-box. A link to a live tutorial (written with WSGIServlets) is available on the project's homepage. The tutorial is also included in the distribution along with a complete API reference manual.
1.5. Discontinued/Inactive Frameworks
The following frameworks are either discontinued, in that their developers may have stated that they no longer maintain the code, or appear to be inactively developed or maintained, in that the Web site for the project has remained unchanged for an extended period of time.
4Suite (the server product seems to receive relatively infrequent updates and the site is often down)
Crusader is a powerful application server for Python based upon a scalable, extensible and easy-to-use general purpose server framework.
Cymbeline (1.3.1 Released 2005-12-09) an application server framework, including functionality such as DB and arbitrary object pooling, Web servers, persistent object repository, and a text console. As of 2013-08-13, this is a dead link.

Pyroxide is built atop Apache's mod_python. It uses the MVC (model-view-controller) pattern and other classic object oriented patterns throughout. It abstracts the mod_python layer presenting a very sensible object oriented framework so that the developer deals with HTTP Requests, HTTP Responses, Page Controllers, Views and domain model objects. It integrates very well with AJAX frameworks such as Prototype and Mochikit. It comes with an elegant ORM framework and runs with Zope Page Templates (Simpletal project) out of the box. (site says: "Please note that this project is dead" and directs people to Django and/or Pylons)

I simply have no time for this venture, seeing as how I am working towards my masters..."; 2013-08-13, dead link)
1.6. Books and Articles
Steve Holden wrote a book on Python Web Programming. The book from John Goerzen, Foundations of Python Network Programming, can also be useful. O'Reilly's Programming Python 3rd Edition has 500 pages on Internet programming, including 250 on Web scripting. Finally, check out the Web Programming chapter in Core Python Programming by Wesley Chun -- there is also a small section elsewhere on Web APIs.
The Zope 3 Quick Start Guide gives a short introduction to Zope 3.
1.7. Content Management Systems
Content management systems (CMS) often allow you to build applications like functionality upon them and typically provide many of the facilities seen in full-stack frameworks. See ContentManagementSystems for more details.
1.8. Web Components
Some frameworks promote interoperable components for things like templating/output and authentication/authorization, and so you might see users of different frameworks actually using the same component or library. See WebComponents for details of such components.
1.9. Web Client Frameworks
In contrast to server-oriented frameworks which may offer AJAX (asynchronous JavaScript and XML) support by serving pre-packaged (inflexible and highly specific but otherwise very useful) JavaScript components, and offering server-side support for requests made by such JavaScript components, Web client frameworks take more direct advantage of the dynamic capabilities of browser engines. Ways in which the full potential of browser engines can be realized are, for example, by compiling Python code into JavaScript or by embedding a Python interpreter into the Web browser itself. In some cases, Web browser engines can be run within separate customized applications rather than in a "web browser" per se. See Web Browser Programming for details.

1.11. Editorial Note
The above lists should be arranged in ascending alphabetical order - please respect this when adding new solutions. When specifying release dates please use the format YYYY-MM-DD.
Some special notes to contributors to this page who like to assume an advocacy position when "reorganizing" the content:
Do not remove editorial guidelines: when people do this it not only indicates that they do not care about such guidelines, but it also leads others to believe that the page never had any structure or purpose.
If you must change the categories used on this page, at least attempt to assign all frameworks to meaningful categories. Do not invent special categories in order to elevate the profile of certain projects. Do not merge categories and put frameworks into a miscellaneous category.
Do not add links to projects unless they are Web frameworks. Instead, use the WebComponents, WebServers, Templating pages, or any page referenced by WebProgramming.
Some frameworks are not actively developed or maintained. Do not just move entries into the "Discontinued/Inactive Frameworks" section without at least doing some investigation first.
Popular is a bit of an arbitrary classification. For something to be considered popular a good guideline would be that it is in the top 4000 packages as per Top PyPI Packages.
And some basic editing advice: use the preview button when making edits, rather than leaving tens of micro-changes in the history.
